Odd one out: 6, 9, 15, 21, 24, 28, 30a)9b)30c)28d)21Correct answer is ...

To find the odd one out from the given sequence, we need to analyze the pattern or rule that governs the sequence.
Let's observe the given numbers:
6, 9, 15, 21, 24, 28, 30
- The numbers in the sequence are not in ascending or descending order.
- The difference between adjacent numbers is not constant.
Observations:
- The numbers 6, 9, 15, 21, 24, 28, 30 do not follow any arithmetic or geometric progression.
- However, if we look closely, we can find a pattern:
- The numbers 6, 15, 24 follow an increasing pattern with a difference of 9 between each number.
- The numbers 9, 21, 30 follow an increasing pattern with a difference of 12 between each number.
- The number 28 is the only one that does not follow this pattern.
Conclusion:
- The number 28 is the odd one out because it does not follow the pattern observed in the rest of the sequence.
- Therefore, option C: 28 is the correct answer.
